The various technical effects that can be produced by the preferred technical solution among the various technical solutions provided by the present invention are described in detail below.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] The present invention provides a soil-spraying greening slope protection structure, comprising:

[0008] An anchor, arranged on the slope surface;

[0009] A protective net fixedly connected to the anchor;

Therefore, wheat straw, as a common agricultural waste, is fully exploited in this soil spraying greening slope protection structure, realizing the full reuse of wheat straw as an agricultural waste, while enabling the overall structure to be sustainable.

[0033] As an optional implementation, the soil-seeding greening slope protection structure further includes a cushion block 3 , which is arranged between the slope surface 2 and the protection net 4 to form a gap between the protection net 4 and the slope surface 2 .

[0034] Specifically, the protective net 4 in this embodiment is a wire mesh with a diamond structure, and the pads 3 are arranged at the corners of the diamond structure. The thickness of the pads 3 is set to 2 / 3 of the thickness of the spraying, so as to improve the spraying greening effect.

[0036] Such an arrangement can make the connection stability of the protection net structure better, improve the stability and safety of the protection net 4 when in use, and increase the life of the soil spraying greening slope protection structure.
